MnOOH纳米棒的低温水热合成

Low-temperature Hydrothermal Synthesis of MnOOH Nanorods

以KMnO4和N4(CH2)6为主要原料,在130℃反应16h,水热法制备了MnOOH纳米棒,并利用X射线粉末衍射(XRD)、透射电子显微镜(TEM)和高分辨透射电子显微镜(HRTEM)等手段对产物进行了表征．探索了KMnO4和N4(CH2)6间的摩尔比以及反应温度对合成产物的影响．实验结果表明:产物为具有单斜结构的MnOOH纯相,形貌为棒状,呈现单晶特性．

MnOOH nanorods were synthesized hydrothermally at 130℃ for 16h, by using KMnO4 and N4（CH2）6 as main materials. The as-prepared samples were characterized by X-ray powder diffraction （XRD）, transmission electron microscope （TEM）, and high resolution transmission electron microscope （HRTEM）. The effects of both molar ratios between reactants and reaction temperature on the products were investigated. The results show that the as-prepared MnOOH nanorods are with a monoclinic single phase, rod-like morphology and single crystalline nature.
